Description
The MEGABRAS model MD-5060x digital intelligent megohmmeter is a versa-
tile, robust and easy-to-use equipment. It uses an efficient well experienced
technology, which provides reliable, safe and accurate measurements of insula-
tion resistances up to 5,000,000 MΩ @ 5 kV, with 4 pre-selected test voltages:
500 V – 1 kV - 2,5 kV – 5 kV, with the possibility of increasing or decreasing
these values in steps of 100 V or 500 V.
A state-of-the-art microprocessor controls the equipment operation and enables
the incorporation of advanced features which make measurements easier:
•
Auto-range selection
•
Built-in printer enabling tests recording.
•
NVRAM memory, enabling storing up to 4000 readings to be later downloaded
to an IT equipment.
•
Built-in chronometer, indicating elapsed time, in minutes and seconds, since
the test started.
•
Real-time clock, indicating hour, minutes and calendar.
•
Voltage measurement, really applied during the test.
•
Polarization index calculation and automatic indication (PI - Polarization In-
dex).
•
Dielectric absorption index calculation and automatic indication (DAI - Dielec-
tric Absorption Index).
•
RS-232 output with optical insulation for the acquisition of readings carried out
with software and hardware.
•
Timer enabling programming of test duration up to 30 sec., 1 min (absorption
index), 3 min, 10 min (polarization index) and 30 min
•
SVT - Step Voltage Test
•
Programmable limit. It makes it possible to carry out "Pass-fail test".
•
Switchable filter to remove external noise interference.
